------------------------------------------

Thanks for the report Todd. If remember that I have done terasort long time ago, and the counter was accurate, will look into it.

> After running a terasort, I see the spilled records counter at 5028651606, which is about half what I expected to see. Using the non-native collector I see the expected count of 10000000000. It seems the correct number of records were indeed spilled, because the job's output record count is correct.
